How to choose a pumping station
A pumping station differs from a conventional pump in that it can work in a fully automatic mode, providing water to your home or area. That is why pumping stations are used as a basis, say, for water supply or automatic irrigation. What to look for when choosing a pumping station?
Pump type. Pumping stations are equipped with single-stage vortex and multistage pumps. The difference between them is that in the first case there is only one impeller, and in the second there are several of them. Single-stage pumps are cheaper and easier to build, which means they are less likely to break down. Multi-stage - more complicated, more expensive, but at the same time quieter and more powerful.
Electric motor power. This parameter shows how much energy the pumping station will consume. This parameter does not directly affect performance - it all depends on the efficiency of the installed motor. However, according to this indicator, one can roughly judge how long the motor will last and how reliable it will be - low-power an engine that is constantly working at its limit is likely to kick in before a powerful engine that works half-heartedly. Typically, the capacity of pumping stations ranges from 0.5 to 1.5 kilowatts.
Suction depth. The higher this parameter, the more difficult the conditions the pump can operate. For example, if the suction depth is 10 meters, the pumping station will be able to pump water from an open reservoir or a shallow well. A depth of 20-30 meters is enough to use a station with an artesian well.
Ejector. This design element makes it possible to increase the force and depth of suction without increasing the power of the electric motor. The ejector can be built-in or remote. The first is located directly in the pump casing: it is quite noisy and not very efficient, but an inexpensive solution, which, as a rule, provides suction from a depth of 10-15 meters. The remote ejector is submerged directly into the water. A pump with a submersible ejector is quieter, and water can be sucked in from a depth of up to 30-50 meters, but this the structure is somewhat more difficult to operate and repair, it requires laying a second, recirculating pipe and costs expensive.
Hydroaccumulator. This word refers to a water storage tank. It is needed in order to maintain constant pressure in the system and not turn on the pump every time someone turns on the tap in the kitchen. The volume of the tank can be from 20 to 200 liters, but it should be borne in mind that water will not be there more than half - the rest of the volume is occupied by air, which allows you to maintain a constant pressure. The larger the accumulator, the better, of course. But at the price of a pumping station, it is the large tank that beats the most sensitively.
Aggression. It is measured as the height of the water column. To determine how much head you need, use a simple formula: H = Hn + Hi + L / 10 + Hd, where:
- Hn - water pressure in the system (usually in the region of 1.5-3 atmospheres),
- Hi - suction depth of the pumping station,
- L is the distance from the pump to the house,
- Hd is the height of the supply points (taps, showers, cisterns, etc.) above the supply line.
Performance. This parameter determines how much water a pumping station can supply per unit of time (usually it is measured in cubic meters per hour). To calculate the optimal performance, it is enough to add up the volume of water that is consumed by all delivery points. Approximate indicators are as follows:
- mixer - 0.6 cubic meters / h;
- shower - 0.8 cubic meters / h;
- toilet bowl with a cistern - 0.3 cubic meters / h;
- dishwasher - 0.6 cubic meters / h;
- washing machine - 0.7 cubic meters / h.
It makes no sense to overpay for excess power and head, because this means a pumping station with a more powerful motor, and therefore with a higher energy consumption.
Materials. The body, storage tank and working group of the pumping station can be made of different materials: plastic, steel, cast iron, aluminum, bronze, etc. Plastic is cheap and not susceptible to corrosion, but it is a fragile and not particularly reliable material from which the housings of inexpensive pumping stations are made. Steel is distinguished by its moderate cost and high strength, but it is susceptible to corrosion - it is used for the manufacture of housings and accumulators of stations in the middle price category. Cast iron is heavy and rather brittle, but inexpensive and much less susceptible to corrosion than ordinary steel, so storage tanks are also made from it. Finally, non-ferrous metals such as aluminum, bronze or brass are almost non-corrosive, but they are quite decent, so they are used to make parts for pumping stations of the highest price category.
Automation. A special electronic relay is responsible for the pumping station to work independently and to regulate the pressure in the system itself. It is desirable that it be equipped with protection against dry running and overheating - this will ensure long-term and stable operation of the station.
Installation method. Pumping stations can be surface or buried. The first ones are installed on the surface of the earth: in a separate room or in a special pit - usually these are inexpensive options for home use. Buried pumping stations are distinguished by quiet operation and very high performance with a suction depth of up to 300 meters, they are expensive and are mainly used in the professional field.

The best pumping station with a suction depth of 10 meters
1. Metabo HWW 4000/25 G (1100 W)
Surface type pumping station, designed for horizontal installation. The 1100 watt motor provides a suction depth of up to 10 m, a maximum head of 46 m wc and a capacity of 4 cu. m / hour. The capacity of the accumulator is 24 liters - enough for arranging a water supply system in a small house with a couple of residents or an automatic irrigation system. The body is made of pretty decent metal, but with plastic elements that tend to wear out rather quickly. Perhaps the main problem noted by almost all users is the high noise level. But at a price of 8,000 rubles for such a device, this does not seem like a big trouble.

FAQ
Why doesn't the pumping station turn off and pump water?
Apparently, problems with automation. Fiddling with relays without the appropriate skills, most likely, does not make sense. The water supply line may be clogged. In any case, it is better to contact the service.
The pumping station is slowly gaining pressure - what is the reason?
There can be a lot of reasons. Garbage in the pipe or clogged ejector, insufficiently powerful and efficient motor, flying electronics - only the master can answer this question after diagnosing your equipment.
